Bec, I remember asking the same thing. Emma slept beautifully during the day & I was worried about her not sleeping at night. I never knew about the noise issue though until I read this! that explains a lot! Emma just worked it out for herself during those first 4 weeks or so. It is tiring during that time, but it definately does get much easier. I use a dummy with Emma for that sucking instinct. I dont know if you want to use a dummy or not, but that is another option if you are getting sore from the sucking.
